The most-used names for this grade.About Non-magnetic steels
Non-magnetic steels are alloy steels designed to have very low magnetic response while retaining useful mechanical strength and ductility. They are used for components and structures where magnetic interference must be minimised, including specialised electrical, laboratory and mechanical equipment.
This describes the material class as a whole. Always confirm the individual grade against the standard before ordering.

Chemical composition
10 elements on file · weight %What this alloy is
Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade.

The scale is logarithmic, not the element’s raw share of the alloy — the only honest way to fit 0.01 % and 100 % in one picture, and it means every value here can be compared with every other.

Predicted transformation temperatures
This grade's composition falls outside the published model's validated range (a low-alloy composition window), so no transformation temperature is predicted here.
Physical & mechanical properties
An absent property means we hold no value for it — it is left out rather than estimated, interpolated from a neighbouring grade, or filled from a handbook. It does not mean the property is undefined for the material.
Similar grades — and why
Selection rule, stated so you can disagree with it: same number class 1.3, a shared category, and a published range for Mn / Cr that overlaps this grade’s. These are neighbours in composition space — they are not equivalents, and none is claimed to be interchangeable with this grade.
